IWF Inband Tone Option

This option enables the Oracle Communications Session Border Controller to send a progress indicator (PI) =8 in an H.225 message when an SDP is received in a provisional message. In effect, this option sends network announcements inband. It is also applicable because in some networks H.323 endpoints support early H.245.

The H.323 inband tone option is enabled by adding the inbandTone as an option in a configured H.323 stack.

When this option is not used, the ringtone is generated locally (NO PI=8 in PROGRESS OR ALERTING) is the default behavior.

IWF Inband Tone Configuration

To configure the IWF inband tone option:

  1. In Superuser mode, type configure terminal and press Enter. 
    ORACLE# configure terminal
  2. Type session-router and press Enter to access the media-related configurations. 
    ORACLE(configure)# session-router
  3. Type h323 and press Enter. 
    ORACLE(session-router)# h323
  4. Type h323-stacks and press Enter. 
    ORACLE(h323)# h323-stacks
ORACLE(h323-stacks)#
  5. Use the ACLI select command add this feature to an existing H.323 interface. 
    ORACLE(h323-stacks)# select
  6. If you are adding this service to a new H.323 interface, type option inbandTone and press Enter.

    ORACLE(h323-stacks)# option inbandTone

  7. If you are adding this service to an H.323 interface that already exists, type select to select the interface to which you want to add the service. Then use the options command and prepend the option with a plus (+) sign.

    • If you know the same of the interface, you can type the name of the interface at the name: prompt and press Enter.

    • If you do not know the name of the interface, press Enter at the name: prompt. A list of interfaces will appear. Type the number corresponding to the interface you want to modify, and press Enter.

    • If are adding service to an existing interface and type in the option without a plus (+) sign, you will remove any previously configured options. In order to append the new option to the options list, you must prepend the new option with a plus sign: options +inbandTone.
